-20x+15x-10x=6
Multiply both sides of the equation by 60, the least common multiple of 3,4,6,10.
-5x-10x=6
Combine -20x and 15x to get -5x.
-15x=6
Combine -5x and -10x to get -15x.
x=\frac{6}{-15}
Divide both sides by -15.
x=-\frac{2}{5}
Reduce the fraction \frac{6}{-15} to lowest terms by extracting and canceling out 3.
